VALVE DEVICE FOR ACETYLENE-LAMPS AND THE LIKE.

essence.

To au whom it may concern:

Be it known that l, GEORGE R. SHANKLIN, a citizen of the United States, residing at tlpringlield, in the county of Sangamon and tltate of lllinois, have invented certain new and useful Improvements in Valve Devices for acetylene-Lamps and the like, of which the tollowing is a description.

My invention belongs to that general class or acetylene lamps provided with valves which are particularly designed to control the liow or ieed oi' the fluid to the calcium farbid. lt has tor its object the production oit a simple, durable and effective valve de vice for the purpose described, that is not likely to clog up with use, and that is reliable and durable in its operation.

rllo this end my invention consists in the novel construction, arrangement and coinbin ation oi' parts herein shown and described and more particularly pointed out in the claim.

ln the drawings, wherein like reference characters indicate like or corresponding parts,

Figure 1 is a vertical .cent/al section through an acetylene gas lamp of well known torni equipped with my invention;

Fig. 2 is a similar section of the lower part o1" the water tube and valve construction on an enlarged scale;

lll`ig. 8 is a transverse section on line 3 3 olf Fig. 2; and

l? ig. 4 is a similar section on line i-ll ot liig. 2.

ln the drawings, 1 represents the water chamber of an acetylene gas lamp of the kind which is usually used by miners. Q is the carbid chamber, the two being adapted to be connected by a screw threaded connection as at 3. LlisI a water filling opening provided with a cap 5. The gas generated in the chamber' E2 escapes through the tube 6 which is suitably equipped with a burner tip when in use.

'i' is a water tube supported in the top olf the water chamber 1 and extending downward therethrough into the carbid chamber, terminating preferably well within said chamber so that when in use the end will be within the body of carbid. The lower end Speifwaton 0f Letters Patent. Patented Mar. 23, 1920.

Application filed May 24, 1918.

Serial No. 236,311.

ot' the tube has formed thereon a valve seat S. A sleeve 9 iirinly secured upon the tube and extends well below the end thereof so that the valve operating within the sleeve shall at no time extend lbelow the bottom thereof. 10 is a valve stem loosely extending through the tube 7 and carrying upon its lower end a valve 11 arranged to seat upon and coperate with the valve seat on the end of the tube to control the tlow of water passing therethrough. The upper end ot' the valve stem 1() is preterably secured to a thimble 12 which screw threaded at 13 into the upper end ot the tube 7. The end ot the stem 10 which extends through the upper end of the thimble 12 is bent over asat 1li to afford a convenient means tor turning the valve stem to regulate the action oi the valve. Arranged in l inc with the junction ot the valve seat S and the valve 11, the sleeve 9 is preferably provided with a plu 1ality of slotted openings 15 so that as the valve is opened, the fluid passing through the tube may readily escape outward through the sleeve. The valve is also of such `relative size as to provide a space around the outer edge thereof between the valve and the sleeve as at 16, so that the fluid may readily escape at that point also.

The inode of operation is: apparent and requires no description.

Having thusdescribed my invention, what l claim as new and desire to secure by Letters Patent is In a valve construction for acetylene lamps and the like, the combination ot' a vertically disposed fluid tube having a substantially continuous peripheral wall free from projections, the lower end of said tube terminating in a valve seat, a valve stern loosely projecting through the tube and terminating at its lower end in a valve to engage said seat, the stem being adjustable whereby to regulate the adjustment ot the valve on its seat, and a sleeve lixed in position on the tube at the lower end thereof and wholly supported therefrom, the said sleeve being in closed relation at its upper end with the wall of the tube and `projecting a considerable distance below the lower end of the tube and all ot' the valve parts, whereby to constitute an inolosing housing for signed my name n the presence of two subthe lowe' eld ofthe tube and valve parts, scrbing Witnesses. and sai s eeve avn an unobstructed' f T opening Yat its lower 1d and peripheral GEORGE R' SHANIXLIB 5 openings in substantial alinement With the Witnesses:
